EGG-TESTER.

Application led January 7,` 1914. Serial No. 810,81.

T0 aZZ w71 om it may concern Be it'known that I, J AMES HALLEY, a

citizen of the United States, residing at Keytesville, in the county of Chariton and State of Missouri, have invented certain new anduseful Improvements in Egg-Testers. of which the following is a specification. My invention relates to improvements in egg testers and, has particularreference to electrically operated means of this character.

An important obiect of this invention is to provide an egg tester of the above mentioned character, including a source of current, the entire apparatus being portable.

,A 'further object of the invention is to provide novel and simple means for closing the circuit to cause an electric bulb to glow in suitable proximity to an egg, wherebv the same may be tested.

' A further object of the invention is to provide means whereby the electric bulb may be made to intermittently glow upbn the movement of an egg into suitable proximitv thereto, or made to'permanently glow, at will. l

A further obiect of the invention. is to provide means of the above mentioned character, which are simple in construction, inexpensive to manufacture, convenient in use, and durable.k

Other obiects and advantages of this invention will b e apparent during the course of thefollowing description.

In the accompanving drawings forming a part of this specification and in which like numerals a're employed'Y to designatelike parts throughout-the same, Figure 1 is a front elevation of apparatus embodying my invention, Fig. 2 i's a rear side elevation of the same, Fig. 3 is@ transverse sectional view taken on line 3--3 of Fig. 2, Fig. 4 is a longitudinal sectional view taken on line 4-4 of Fig. 3, Fig. 5 is a plan view of the apparatus, parts being broken away, and parts removed, and Fig. -6 is a detail sectional view through one of the bulb holding casingsL Inthe drawings, wherein is illustrated a preferred embodiment of my invention, the numeral 10 designates an outer casing or shell as a whole, divided by a longitudinal partition 11, into a vertical testing' casing or chamber- 12 and a horizontal storage chamber 13. The testing' chamber or casing 12 is provided at its upper end with a. peep Specication of Letters Patent.

hole or opening 14, and upon its outer wall l5, and near the lower end thereof with a i pluralitylof hand holes 16, which ,are covered by split sections of felt 1T orthe like, serving to permit of the insertion of a hand through the opening 16, and adapted .to fit closely about the same, to retain the test casing or chamber 12 as dark as may be practicable.--1n 'Y formed of wood and the partition 11 thereof is provided with. suitablv spaced openings V18` receiving bodily -reciproc'atory egg receiving cups or receptacles 19, the inner ends of which are closed and the outer ends of which are open and dared. as shown at 20. Each oflthese egg receiving cups or re- ,x The main shell or casi'nglUlismpreferablye.

one end thereof electricalh7 connected with the outeuscrew-threa'ded element 22 of the socket while the opposite end thereof is cnnnected with an inner element 24, insulated from the outer screw-threaded element 22,.

as is the case with the ordinary incandescent lamp or bulb. The socket of the bulb 23 passes through a reflector 25, arranged within the cup or receptacle 19, rearwardly of the bulb 23, suchA refiector having its outer surface concave. as shown.

A circuit is closed to cause each bulb 23 to glow, upon the insertion-vof one end or portion of an egg within the fiaring open end or the mouth of the cup or receptacle 19, and the inward bodily movement of 'the cup or receptacle 1Q bv the egg. To accomplish lthis I arrange 'within the storage casing or chamber 13, near each of the cups or recepment 22 of the socket of the bulb 23. I also preferably provide a clamping or lock nut 29, which is mounted upon the outer end of A the screw-threaded outer element 22 of the electrical bulby socket.

The spring 261 serves? two purposes, tirst as means for 'closing'the circuit to cause' the bulb 23 to glow, and second, as spring meansV to normallyv retain the-cup -or receptacle 19 in its outer position, whereby the circuit is broken. The outward bodily movement'. of
